What do you think? Is this regimen okay for an 11 year old?

That seems a little to harsh for her face. When I was 11, I started getting acne also, but all I did was wash my face twice with some Noxema (when you use it daily, it works miracles to your face!) and my acne got better. My skin was the same and still is the same except for it is leaning towards normal. Now I use the Neutrogena Wave in the mornings. And then I put on a light moisturizer. In the evenings in my shower is use Clean and Clear Oil Free Acne wash and then put on a light moisturizer again. This has worked for me
